SSL certificate not working on second subdomain

Greetings dear community,

I’ve been using Cloudflare for a while now, and everything was going pretty smoothly. I had a SSL certificate working on my wordpress website on
However, I recently (>24h) created a second subdomain, but I can’t get SSL to work on

I’m using Flexible SSL, I have a universal Cloudflare certificates which covers * and Both subdomains have the same DNS configuration in Cloudflare (orange clouds everywhyere), so I really can’t figure out where this problem is coming from.

Hi again. Once again, many thanks for your help. Would you know what might be causing this redirection? I’ve tried setting a rule in my .htaccess to redirect www to non-www, though it only created a redirection loop. I’ve checked all possible options from my provider and couldn’t solve it.
Checking my Cloudflare configuration, both subdomains have exactly the same configuration, so I’m running out of options. My current configuration is as follows:
A / / IP
A / sub2 / IP
A / sub1 / IP
A / www.sub2 / IP
A / www.sub1 / IP
CNAME / www / alias of

I’ve been checking possible ways to find out where this 301 comes from, though I still can’t figure it (e.g.
Many thanks for your time.

Solved by recreating the website from scratch!
